Geoff sits down and has a 1:1 conversation with Professor Thomas Seyfried, a renowned and controversial researcher who authored "Cancer as a Metabolic Disease".  Cancer has generally been considered a genetic disease since its inception, but Professor Seyfried fights against that view and argues that it is a metabolic disease. Encouraging doctors to look into metabolic treatments as the first method to combat cancer cells, Seyfried may have a point. Metabolic treatments include caloric restriction, fasting, and ketogenic diets...all of which Seyfried speculates have the ability to help the body and kill off cancer cells. There are certain bodies of research showing that cancer cells thrive on sugars and amino acids, which metabolic therapies have the potential to control. Could cancer truly be a metabolic disease?
